To do a search and replace I recommend using this:


find . -type f | xargs perl -pi -e "s/foo/mypackage/g"

You can use the pattern to seach and replace recursively all files: where foo is the text you want to replace and mypackage is the replacement text.

Most linux distributions contain a perl script called rename you can use to rename the files and directories.

ie:

rename "s/foo/mypackage/"
